Three words for weather like this

The software that runs the Wall

@ July 2, 2002 9:11 PM in May I have your thoughts on this, please? - Dan H.

can open into other rooms. I was thinking about having a Classroom that we could use from time to time. It would be a place where we could gather on a certain day and time to ask questions of a guest expert. The Wall would continue to run as is when the Classroom was in session, so it would be your choice as to whether you'd like to sit in on the class or just hang out on the Wall. I thought this might be a good place to explore one subject or issue at a time, and in depth. The text would then sit there for a few days for anyone who wanted to view it. What would you think of that? Would that be useful to you? Thanks for your thoughts, and for all that you do for us.

about 50 a day (got the one with your name on it, no worries). What works really well to catch them before they enter the computer is McAfee's Spam Killer. It also catches and deletes all lot of the nonsense email that arrives here every day. Please don't let this upset you; it's just the world we live in. Most are astute enough at this point to not open attachments without scanning them, even when they arrive from folks we know.

And so is

Hot Tech Topics

@ July 2, 2002 6:55 PM in Need fun, interesting facts about heating for newsletter. Rocky

Here's part of one of the tales over there: There was once a time when a square foot of radiation meant, literally, one square foot of surface area on the radiator. When they filled the radiator with 1-psi steam, each square foot of surface would pump out 240 BTUH - as long as the air surrounding the radiator was 70 degrees. Make the air cooler, and the radiator would put out more heat. The opposite also was true. Still is. Toward the end of the 19th Century, foundries began to elevate radiator-making to an art form. To increase the surface area, while decreasing the overall size of the radiators, manufacturers began to give their units more nooks and crannies than a beehive. The challenge was how to measure the surface area of these old beauties. The Dead Men solved the problem in a most ingenious way (and ask yourself if you would have been able to figure this one out.) Now, remember what they were trying to do was just measure the outside surface area of the radiator. Not the inside, not how much space it took up - just the outside. So heres how they did it: They got themselves a big vat filled with paint, which they put on a scale. Next, they plugged all the holes in the radiator, hung it from a thick chain, and then slowly lowered it into the paint. They let the radiator sit in the vat for a while - long enough for the paint to find its way into every cast-iron angle, twist and turn. Then they raised the radiator from the vat, letting the excess paint drip off. They weighed the vat again, knowing that the paint that was no longer inside the vat would now be clinging to the outside surface of the radiator! Finally, theyd put that much paint in a can . . . and then they painted the floor with it. The amount of floor surface they could cover with the paint became the square foot EDR rating of the radiator. Pretty cool, eh? As time went by, they figured out how to measure a radiators output by weighing the condensate that came out of it. After they had this more-modern method worked out, one nostalgic engineer went back and checked it out against the Paint Method. To his delight, the measurements were remarkable similar! Its just that with the Paint Method, they needed really big testing laboratories.

Guys, I hid the photos so that this great thread would fit better on the screen. Just click on the links and they'll open in a new window. Thanks.

you don't know heating? Thanks for sharing all of this with us, Sal. I'd love to be there when the GC hears that Mark is the guy that's making the comfort-related desisions. That's delicious!

of Milton, MA just signed up. The Gathering is the Saturday before Thanksgiving. What a fine time of the year to be in New England. I'm really looking together to having some laughs with you all. Anything can happen at this thing. Probably will!

Sal, please tell us about what you'd like to have in that home that you're having built in the future. Has your reading of the Wall over the years influenced you? How so? Thanks.

for not getting into name-calling, Matt. I thought Sal made his points very well too. Now, how about those heating systems?
